There are only 31 RTC studies. Most of them are very small and not even statically significant. It is a known problem that studies that show no effect or a bad effect are never published due to report and publication bias. So it's better to ignore the not statically significant studies.

So there are only 6 of the 31 RTC studies that are statically significant. If Ivermectin has no effect, we expect to see like 1.5 studies that are "statistically significant" due to a flukes. We don't know how many other studies have been tried but never published, so let's be very conservative and assume that if Ivermectin has no effect, we would get 2 studies that are "statistically significant" due to a flukes.

There are 6. I read a few of them and have very strange things. Not smoking guns, but big red flags.

So ... can you choose your favorite 3 statistically significant? I'll dismiss 2 as flukes and hopefully I can explain why the other study has a very big red flag and is not reliable.
